With a temporary file, there is a good traceback, but working with files
can be slow. When precompiling in memory, it is faster, but that is not
implemented in a way that yields good tracebacks.
> Are people really executing `load` or `attach` in tight loops?
I can't imagine that anyone would do that.
> I think that one should '''always''' have good tracebacks, so I would
always use temporary files.
I completely agree. However, it seemed during the original discussion that
I was the only one who always wanted good tracebacks. And someone made the
switch to memory on purpose, for efficiency reasons.
